RAILROAD-CROSSING.

SPECIFICATION forming part of Letters Patent No. 498,724, dated May 30, 1893.

Application filed June 15,1892. Serial No. 436,872. (No model.)

To all whom it may concern.-

Be'it known that I, HENRY OSHEA, a citizen of the United States, residing at J ohnstown, Oambria county, Pennsylvania, have invented a new and useful Improved Railroad-Crossing, of which the following is a specification.

This invention has for its object to provide a strong, safe and durable crossing for street.

cars over or across steam railroad tracks, which can be put in place without disturbing the latter track; and also to provide a strong and efficient guard for wheels passing over the steam railroad tracks.

In the accompanying drawings: Figure 1 is a plan View of a crossing illustrating the invention. Fig. 2 is a vertical cross section on the line XX Fig. 1. Fig. 3 is a plan view of portions of a crossing rail and main rail with parts broken away disclosing chocks and chock bar. Fig. 4 is a vertical cross section on the line YY, Fig. 3, giving a side View of the chocks and bar. Fig. 5 is a vertical cross section on the line ZZ, Fig. 4. Fig. 6 is an elevation of the parts in Fig. 3,1ooking to theleft, and Fig. 7 illustrates details of the chock detached.

1 indicate the through rails of a crossing, and 2 guard rails, parallel with the through rails, and provided with curved extensions 3 to guide the flanges of wheels passing over the through rails.

4 indicates crossing rails within the through rails and 5 the extension thereof outside of the through rails.

Lying against the through rails on the outside thereof are bars 6 of Z shape as shown, or which may be of any other form desired, and which in practice are secured to the ties and are even at the top with the top of rails 1, to permit the passage of the treads of the wheels overlapping the rails 1. The bars 6 serve to support the extensions 5 of the crossing rails, which extensions abut the bars 6.

The crossing rails 4 and guard rails 2 with their curved extensions 3 are shown as formed in one piece by welding. They may however be united by plates and bolts at the joints.

7 indicate chocks located between one o the bars 6 and one of the through rails 1, said chocks being preferably located in line with the crossing rails 4, but should said rails come opposite to a joint or splice bar on the rail 1, the chocks 7 should then be placed as near to this point as possible. The chocks 7, as here shown, are welded to the bar 6,but may be attached thereto by bolts and nuts.

Between one of the guard rails 2 and the adjacent through rails are placed chocks 8, secured to the guard rail 2 by bolts and nuts or by welding. v

To enable the center portion of the crossing, consisting of the guard rails 2 and crossing rails 4, to be placed in position, the guard rail 2, through rail 1, and Z bar 6, opposite to those just described, are secured by adj ustable chocks, constructed and arranged as follows:

9 is a chock bar, of a length to extend crosswise heneath a guard rail 2, athrough rail 1, spaced from the guard rail and a Z bar 6. The bar 9 is provided near one endon its top with a chock 10, which when in position is located against one side of a 2 bar 6 and beneath its top flange, and is preferably braced by means of a projection 11 thereon, which engages a hole or socket 12, inthe web of Z bar 6. 'The lower end of chock 10 is cut away on one side at 13 to conform to a lower flange of through rail 1 which is seatedtherein. A second chock 14 formed with a depending arm or projection 15, having a recess or pocket 16 in its end, rests on the bar 9 as shown in Figs. 4 and 5, and'is located between the through rail 1 and guard rail 2. The projections 17 formed by recess 16, serve to guide the piece 14 in its lengthwise movement on bar 9 when the parts are clamped in place. The bar 9 is formed on one end with a neck 18, on which is mounted a clamping block 19, movable endwise thereon, and having lips 20 to engage one of the lower flanges of the guard rail 2 and the bar 9. The other lower flange of the guard rail 2 is cut away at 21, as shown in Fig. 4, to afford room for the depending arm 15 of the chock 14 between the adjacent lower flanges of guard rail 2 and through rail 1. The bar 6, chock 10, through rail 1, chock 14, guard rail 2, and block 19 are firmly clamped together by means of a wedge or tapering key 22 inserted through a slot 23in the neck of 18 behind the block 19.

The chocks just described may be readily put in place and adjusted at any point desired between the crossing rails 4 and by drivingthe wedge key 22 into the slot 23, the bar 6, rails 1 and 2 and the chocks and block 19 will be firmly clamped together. Any other form of tightening devices may be employed in place of the wedge key 22, and the construction and arrangement of the chocks may be altered, the essential feature of the invention being an adjustable chock with means for adjusting and tightening it in position. In practice two such checks are employed between the inner crossing rails, as shown in Fig. 1.

By means of chocks as herein set forth, the inner crossing and guard rails can be put in place without disturbing the through rails and the parts will be firmly held in place and can be easily and readily adjusted and tightened when necessary.

I claim- 1. In a railroad crossing, a guard rail in combination with a through rail and a chock between said guard rail and through rail, provided with means independent of perfora- I gether and clamping them.

3. In a railroad crossing, a guard rail i combination with a through rail, an outside bar parallel therewith and chocks between said rail and said through rail and bar, a bar on which said chocks are mounted and means substantially as described for drawing the parts together and clamping them.

4. In a railroad crossing, through and guard rails provided with chocks, the chocks between a through and guard rail on one side of the crossing being fixed and the chocks between a through and guard rail on the other side being adj ustable longitudinally with and transversely to said rails and provided with means independent of perforations in the webs of rails for drawing the parts together and clamping them.

ing the chock to the rails independently of perforations in the webs of the rails.

7. In a chock for railroad crossings, a barprovided near one end with a chock having a projection to engage a bar and at the other with means for adjusting and clamping the chock.

8; In a chock for railroad crossings, a bar provided with a chock near one end,a chock movable lengthwise on the bar and means for adjusting and clamping the chock.

9. In a chock for railroad crossings,a bar provided with a chock near one end, a detachable chock movable lengthwise on the bar and means for adjusting and clamping the chocks.

10. A chock for railroad crossings, consisting of .a bar with a chock near one end, a chock movable lengthwise on the bar and detachable therefrom, a clamping block at the other end of said barandmeans for securing said block to said bar.

11. A chock for railroad crossings, consisting of a bar with a chock near one end, a chock movable lengthwise on the bar and detachable therefrom, a clamping block at the other end movable therewith upon said bar and a wedge key for drawing and clamping the parts to rails. 1

12. The combination with a guard rail, a through rail and a bar parallel with and outside of the through rail, of a bar adjustable longitudinally with and transversely to said rails and bar, a chock piece near one end, located between the bar and through rail, a chock movable on and detachable from the bar, located between the through rail and guard rail, a clamping block on the end of the bar next to the guard rail and a wedge key in the end of the bar adjacent to the clamping block.

In testimony whereof I have affixed my signature in presence of two witnesses.
